California is a beautiful state and Dean and Castiel were hopelessly in love with it. Four years, eight months and forty six days ago they moved into their apartment and settled into their new life. Four years together and they were still going strong, they had any typical relationship. They fought, bickered, laughed, loved, and enjoyed the time they had together because they were meant to be.

The University of California, San Francisco School of Medicine accepted Castiel with open arms when he received an A and B's. Before he had received the results, Castiel went to prom dressed in a smart suit and black tie that made Dean's mouth water in desire. Castiel took Jo as his partner while Balthazar took Pamela. It would be the final night the five of them would be together and it was a night filled with laughs, alcohol, and tears from Jo and Pamela. Castiel didn't regret going and went home to Dean that night full of alcohol and happiness.

Their departure from Washington was a day full of surprises as they packed the Impala with their clothes and possessions and stood in front of Gabriel, Anna, Sam, Jess, and Daniel. Sam after many weeks of persuading and reasoning with had come around to the idea of his older brother dating a younger man. Sam's first meeting with Castiel was awkward as they faced each other and shook hands. A few words were exchanged and Dean along with Jess could only look on and cringe.

"It's only two states away" Castiel murmured when Anna hugged him tight.

"You call me as soon as you get there!" she cried clinging to him.

They left Washington after Castiel said his goodbyes and promises to Balthazar that he would call and come see him soon. Balthazar looked on looking watery eyed and embarrassed by this little fact. It broke Castiel's heart to leave his one true best friend but it was for the best and for his future.

Four years into the future, Balthazar and Castiel are still good friends but with Balthazar travelling and living up to his single life, they rarely saw each other and talked more on the phone.

Castiel was now in his final year of medical school and things looked brighter than ever but no one has the best luck forever and one little change can make a huge difference.

Dean was pouring his morning coffee when he heard Castiel swear very loudly and land out of bed with a thump.

"I'm late!" Castiel shouted coming to the bedroom door and glaring at him.

"No you're not, it's not even nine, Cas" Dean said glancing at their clock.

"Yes and I told my professor I would be in at half eight to go through a test, shit!" he shouted angrily. "This is your fault"

"I apologise for having sex with my boyfriend all night"

"I told you I had to be up early!"

"You spread your legs for me" Dean muttered turning to face him and sipping it. "You loved it, baby"

"No" he scowled looking in the mirror.

"You did, I got to say for our ages…we're bloody good"

"I'm twenty two" he said smugly.

"I'm a lovely thirty before you call me an old man…again!" he said with a frown.

Castiel smirked for a moment before flattening his hair.

"You look sexy"

"I look fucked out"

"It's because you were fucked out"

"For nine hours, Dean? I'm sore!" he growled.

"I lied, I'm not sorry at all for making love to my frankly gorgeous boyfriend who I like to have sex with" Dean said with a smile. Castiel rolled his eyes hiding his own smile and marched over picking up his bag.

"I still blame you, assbutt" he muttered and went to storm out.

"Cas? Castiel!" he called over to him watching him stop and turn around giving him a wounded puppy face. Castiel knew the only time Dean called him by his first name was when he was in his bad books. Dean held out his hand for him and waited for him to come over and take it looking up at him.

"Take a deep breath" he instructed watching him inhale and exhaled softly. "Relax! You're making me edgy, Cas, it's university and you're in your final year. I'm sure Tyler will be okay about you being late"

"I know" he murmured pressing his forehead against his shoulder. "I'm just nervous about the test"

"It'll be okay, you're going to be amazing"

"Are you going the garage today?"

Dean nodded once giving him a soft kiss and nuzzling his cheek gently. "I'll see you later"

"I'll cook?"

"You bet your ass you will" Dean said playfully shoving him away. Castiel smiled walking away and out of the apartment heading towards the university. Dean sighed when the apartment door clicked shut and it went silent. He turned on the radio letting the warm voice of the man talk as he collected his work clothes and got dressed. Dean sacked in the teaching and now worked at their local garage. On Tuesday and Thursday, Dean will teach history to adults and sometimes teenagers in the local high school. It's enjoyable and gives Dean a chance to do both. Recently, Dean had been given the job as manager from his own boss, Joshua; he was getting old and tired.

Dean was overjoyed by this and took the job in full stride. It was good money and was earning them both a living to get by on. Dean looked on at the rumpled bed and smiled softly. They had a healthy relationship and Dean was thankful their little spark was shining bright. Their sex was still amazing and even though they knew every bit of each other, it was still fun to find different ways and to fuck in different places.

He glanced over to the small black and white bundle on a little cat bed in the corner and walked over nudging it.

"Come on, Gem, time to get up" he said peering down at their one year old kitten. She was black all over with bright blue eyes; Dean got her for Castiel on their third anniversary. Gem looked up and meowed softly.

"Have to feed you and go, so come on" he called walking out and hearing her little bell tinkle as she followed him out. Dean knew she didn't understand but still talked to her anyway.

Dean scooped cat food in a bowl and wrinkled his nose at the smell.

"When did I become so domestic?" he murmured shaking his head and going to get his overalls on.

Castiel walked into the café and looked over to the small table and smiled seeing his friend, Lily Grace, sipping coffee. He dropped down on the seat and met her disapproving gaze.

"Tyler will be furious"

"I know, it's Dean's fault"

Lily narrowed her eyes placing her coffee down to regard him.

"Dean, the imaginary boyfriend"

"He isn't imaginary, Lily, I have already explained this! Just because you haven't met him doesn't mean he's not real"

"How long have we been friends?"

"Around a month?"

"No, two months and two weeks" she said with a sniff. "I haven't even seen him"

"You live across town, Lily, and Dean is private, he's mine, and he's away from medical school" he said looking her up and down. Castiel met Lily when he was placed with her. Lily is new to the university after joined later, she spent more time doing nursing and redoing certain exams before joining UCSF and meeting him.

Lily snorted brushing back her dyed brown curls and shrugged. "I'm meant to be one of your best friends, you're one of mine"

"You are! You're never going to let this go are you?"

"Never"

Castiel rolled his eyes at her and looked up at the waitress who brought over his regular coffee. Lily sighed looking away from him; Castiel watched her and despite his own sexuality thought of her as beautiful. Lily had dyed brown curls cascading down her back, big brown eyes framed by curled eye lashes, and a small sweet smile.

"You are one of my good friends, Lily, and not even Michael has met Dean and I have known him longer"

"Just…let me see him…please?" she said with pleading eyes. "Or I will continue to think he is imaginary or your cat"

"My cat?"

"Yes, bestialityis rapid these days"

"You are truly disgusting, Lily"

Lily smirked finishing the rest of her coffee. "Your decision, sweetheart"

Castiel closed his eyes and shook his head for a long moment. "Fine, I have to go see him in his garage at lunch"

"Seriously?"

"If it stops you thinking I am dating and having sex with my cat then yes"

Lily laughed grabbing her bag and beckoning at Castiel to follow her as they went to the lab. Castiel loved medical school. He loved learning about the human body, how it works, learning how to fix, mend, treat, and generally become his dream. He sent regular updates to Gabriel and Anna who loved hearing about his life in university.

Anna now lived in her own little apartment with her friend, Rachel, and Gabriel lived in their old house on his own.

It hit 12.30pm when Castiel met Lily outside; he looked up to the bright blue sky and sighed. It was the middle of April and California was already edging towards a hot summer.

"How far away?"

"Fifteen minutes" he said leading the way as he headed towards the garage. Lily walked in step with him.

"So, you have been with this guy for four years?"

"Yes, nearly five years in a few months' time" Castiel said smiling.

"Wow that's a long time!" she said amazed and fifteen minutes later they arrived at their destination. Castiel moved ahead of her and stepped inside scanning the area.

"Dean?" he called banging on the Mercedes in the garage.

Dean slid out looking up at him between his legs. "Well here's a familiar sight"

"What?"

"My head in between your legs" he said with a small smile.

"Hilarious" Castiel said dryly. Dean pushed up and looked over to Lily who was staring at him open mouthed.

"Who's this?"

"Lily, my friend" he said looking over to her and smirking. "He's my cat"

"What?" Dean said looking over at him confused.

"Personal private joke" he replied pressing a hand to his chest and kissing him sweetly. "I came to see you"

"For what?" Dean said wrapping his arms around his waist.

"What do you want for dinner?"

"You couldn't text?"

"Dean, every time I text you reply "Whatever you feel like" and when I do…you turn your nose up at it"

Dean rolled his eyes and looked up at the ceiling for a few moments.

"Burgers"

"Again?"

"Let's get takeout" he murmured with a smirk.

"Okay" Castiel murmured pressing his lips against his looking into his eyes. "Gem okay?"

"Yeah, she'll play with her string" Dean replied amused. His eyes flicked over to Lily watching them in surprised fascination.

"You better go"

"I know" Castiel murmured and smiled when Dean moved his head to press a gentle kiss under his ear. "I'll see you at six if you're done"

"Hopefully" Dean replied with a sigh looking back to the Mercedes. "The owner is a bastard"

Castiel chuckled and nodded. "Burgers again, California has struck your heart"

"Yep" Dean said with a wink watching him walk out and join Lily. Dean nodded at her while she gaped for a long moment before joining Castiel.

"Holy shit!" she cried when they walked down the street. Castiel laughed lightly taking out his bottle water and sipping it. "He's real"

"I don't have sex with animals, well apart from him"

"He's gorgeous! How old is he?"

"Thirty" he murmured with a hint of pride.

Lily looked back at the garage and swallowed hard. "You're seriously lucky, he reminds me of…Mark"

Castiel stopped looking over to her. "Your dead childhood sweetheart?"

"Yes, he died in a car accident" she said looking back to Castiel. "He treated me the same way he treated you back then"

"Oh" he breathed and shifted feeling uncomfortable. "I am sure you'll find someone like him again, Lily, there is someone for everyone"

Lily nodded looking down at the ground and back up to Castiel with hooded emotionless eyes.

"Yes, I will"

Castiel smiled at her and continued to walk on while Lily looked back to the garage. Her heart skipped a little beat and she bit her lip contemplating. Thoughts and musings flooded though her mind and she exhaled following after Castiel. Lily hated her own mind but it was so damaged already with her past.

~0~

Castiel was exhausted when it finally hit 6pm and he waved Lily off in her car. He was walking down the road towards the garage when his phone buzzed and rang, Castiel smiled when he saw the name.

"Balthazar" he greeted.

"How is the love of my life?" Balthazar said coolly.

"I don't know why don't you go ask him or her?" Castiel responded dryly.

Balthazar chuckled putting his feet up on the table and glancing outside. "I'm currently back in Washington but I have a surprise"

"What?"

"I'm coming to see you on Thursday"

Castiel gasped feeling a flood of overwhelming happiness inside him at the thought of seeing him for the first time in three weeks.

"Brilliant, it's time for a catch up"

"Will lover boy mind?"

"No, Dean is okay with you and you know he is"

"He hates me!"

Castiel groaned hating their long time feud over nothing at all. Nothing seemed to work to fix it and Castiel had given up trying.

"Whatever" Balthazar murmured grimly "How's uni?"

"As Dean would say, it's awesome"

"You sound like him, you two are made for each other" Balthazar said in disgust.

"Well four years is a long time" Castiel said arriving outside the garage. "I have to go, I'll call you on Wednesday"

"Fine, see you later, darling" Balthazar said and hanging up.

Castiel chuckled pocketing his phone and looking inside to see Dean wiping his greased hands.

"Hey" Dean murmured when he stepped inside with a smile.

"How's your day been?" Castiel said leaning on the hood.

"Awful, the owner of this fucking car is a multi-millionaire stopping in town and he said I must fix problem or he won't pay me…fucking dick" Dean grumbled kicking the tyre. "He wants it done for tomorrow morning…I'm not done yet so no dinner till later"

Castiel nodded with a frown looking over at him in his overalls and bit his lip.

"Fancy working up an appetite and getting revenge at the same time?"

"What?" Dean said eyeing him carefully when he walked over looking up at him mischievously.

"Well…when multi-millionaire comes to collect his car and pick on everything…you can nod and smile knowing you and the love of your life had sex in his backseat"

Dean pressed his lips together amused and laughed shaking his head.

"You naughty boy"

"I am…you'll have to punish me and I want to choose my own punishment. Let's have sex in that backseat" he whispered pressing against his chest.

Dean swallowed hard and glanced over to the open door of the garage. "Okay, two seconds"

Castiel watched as he brought the shutters down and looked back towards him. Castiel launched himself over to him kissing him fiercely. Dean groaned backing him up against the car prepared to take full control but was beat to it when Castiel spun them around as he opened the door shoving Dean inside. Dean watched as he slid up the leather to see Castiel strip off his t-shirt and throw it on the steering wheel.

A groan escaped his lips as he shrugged down his overalls and they wiggled and moved till they were mostly naked and pressed against each other in the small space. Dean kissed him with hot open mouthed kisses down his jaw and throat as Castiel pulled out lube and wriggled and twisted his fingers in Dean's hole.

"Shit" Dean hissed when he was opened wide enough for Castiel. Dean spread his legs wider feeling sweat coat his back and forehead already. The leather stuck to his ass and back as he moaned breathlessly when Castiel slid deep inside him. It was quick and swift just the way they liked it. Dean gripped Castiel's ass tight kneading them and urging him inside deeper as they rocked together. Castiel slammed his palms down on the seat next to Dean's head as he thrusted deep down inside Dean who cried out.

The car rocked underneath them as they moved fast and locked together perfectly. It was intense and exciting by the possibilities of getting caught and in the tight space. Castiel moaned throwing his head back when Dean's nails pressed into the tender skin of his ass leaving red encircles that would leave marks.

"Dean" he moaned finding his mouth and licking his tongue inside it tasting shit coffee and something sweet like a doughnut. Dean gasped into his mouth when his hard cock rubbed against Castiel's stomach and erupting his orgasm squirting his come over his skin. Castiel arched his spine climaxing moment later inside Dean who gasped when the warm liquid flooded inside him.

Castiel gasped collapsing on Dean who groaned and laughed.

"Fuck" he breathed rubbing a hand down his sweaty back. Castiel nodded moving up to look at him and smiled.

"Sex in another man's car can be erased from the list"

"You're amazing"

"I know, I love you by the way"

"Good job" Dean murmured stealing a kiss and trailing his tongue across his bottom lip. Castiel smiled looking at the steamed windows and tracing his finger into them.

Cas loves Dean.

He's mine and this car sucks.

"Cas!" Dean said peering up at the steam on the window. "You're a child!"

"It's funny" he teased looking down at him and dropping back down on his chest. "Up for round two?"

"Is this revenge, baby?"

"Maybe"

Dean rolled his hips grinding them slowly against Castiel's who smirked and kissed him hard thrusting his already hard cock in him.

"We're made for each other apparently" he whispered and smiling when Dean rolled his eyes.

"You're always cheesy during sex"

"Natural gift" he gasped pushing his tongue into his mouth as they fucked slowly this time. It was about taking time and enjoying each other's company.

Unaware to both of them at all, a figure watched under a spotlight next to her silver car staring at the now closed car. Lily didn't know why she was here but it was a natural urge. Dean reminded her of her childhood sweetheart and her one and only love. She stared at the garage door feeling sick and guilty. Lily had watched their little exchange feeling an overwhelming sense of loneliness as her mind told her she would never, ever, get that again and she was alone in the world. It seemed like there one more danger in the world in the form of something so innocent.

A/N: You have your sequel! I have an idea, it may ruin it, but you begged me for one. It's four year in the future because that's how long medical school is and I wanted them still young and fresh.

Enjoy, please give me your feedback, and I will try my best to update quick.
